COVER FOR CONTAINERS Filed Aug. 18, 1950,

INVENTR-S IL-1m ALA 1mm I 0 ARTHLLR D- 1EQELNE www Jarr-r-oqwz a Patented Aug. 1 8, 1931 UNITED STATES PATENT OFFEQE THOMAS W. MILLER ARTHUR D. GREENE, OF ASHLAND, OHIO, ASSIGNORS TO THE FAULTLESS RUBBER COMPANY, OF ASHLAND, OHIO, A CORPORATION OF OHIO COVER FOR CONTAINERS Application filed. August 18, 1930. Serial No. 476,218.

This invention relates to covers for containers and has for its object the provision of an improved cover, more particularly adapted for use in connection with hot water bottles or the like, such as ice bags.

In the drawings accompanying this specification and forming a part of this application we have shown, for purposes of illustration, one form which our invention may assume, and in these drawings:

Figure 1 is a plan view of an embodiment of the invention,

Figure 2 is a sectional view corresponding to the line 24-2 of Figure 1,

Figure 3 is a sectional view corresponding substantially to the line 3-3 of Figure 1, while Figure 4 is a fragmentary side elevational view of said embodiment.

The cover hereinafter described is shown as used in connection with a rubber hot water bottle 9 having an apertured tab 10, a reduced neck 11. a flared mouth 12, and an apertured tab 13.

The cover, indicated generally at 14, comprises oppositely disposed side walls and 16 of rubber sponge, secured together along their bottom edges 17 and their side edges 18, approximately to the points 19, as by rubber cement, the cement being omitted along the bottom edges to provide the aperture 2O for the tab- 10 of the bottle 9, and also omitted from the points 19 outwardly, so as to form the loose mouth portions for the receptacle.

The walls 15 and 16 of sponge rubber are reenforced along their inner surfaces by skins or rinds 21, left thereon, after the rubbersponge is molded. The outer surfaces of the walls 15 and 16. however, have the skin, resulting from molding, removed therefrom, so as to expose the cellular structure of the rubber sponge throughout the exterior surfaces of the walls 15 and 16.

A plurality of apertures 22 are formed in each of the'walls 15 and 16 providing for the escape of heat from the hot water bottle 9 by radiation, and the number of apertures may be varied, depending upon how slowly such escape is desired.

will be appreciated that the exposed cutrubber sponge presents a velvety exterior surface pleasant to the touch and attractive in appearance; furthermore dueto the formation of the exposed cellular structure of the rubber sponge a surface is provided which'tends to remain wherever placed and which is not likely to slip from the desired position, but rather clings to such position byreason of vacuous suction set up by the yieldable cellular porous formation.

Also due to the formation of the material heat is retained longer than would ordinarilybe the case, though there is no possibility of the patient being burned as the material does not become hot, but is aerated, and prevents extreme heat being transmitted to the patient. The openings in the walls of the cover deter mine the period over which the heat is retained, the greater the number and larger the size of the holes, the shorter the period during which the heat is retained, whereas reduction in the number and size of holes in sures the retention of the heat over a longer period.

It will be understood by those skilled in the art that the embodiment described herein accomplishes at least the principal object of our invention: it also will be apparent that the invention is adaptable to uses and has-advantages other than those herein specifically referred to; furthermore it will be appreciated that various changes and modifications may be made without departing from the spirit of the invention; and accordingly it will be understood that the embodiment herein disclosed is illustrative only and that the invention is not limited thereto.
